PLL Episode 3x18 - Dead to Me

Clues in this Episode that Aria isA

Emily recently was drugged the night that Ali's body was dug up and taken out of her grave. Emily and the girls were found at the grave that night that it happened, but Emily doesn't remember at all how she got there the other three girls just followed her there. Emily keeps getting flashbacks about that night and members parts of it depending on what random things she sees and what she can connect to that night trying to remember what actually happened. Emily most recently remembers someone in a black hoodie digging up Alison's grave. We are shown this black hoodie and we can see someone trying to dig it up. If you look closely the person trying to dig up the grave has a piece of long brown hair sticking out if their hoodie. That hair looks almost identical to the color of Arias hair. Also it is the same texture as well. I don't think it is a coincidence that Arias hair looks identical to the one that is sticking out of the black hoodie that is digging up Alison's grave. Does this mean that Aria was involved in digging up Allison's grave? It would explain why she's always been wearing these bone in skull shirts all the time!
